# Structured data (JSON-LD) check

> Validates schema.org JSON-LD on every crawled page against Google's rich-results eligibility rules.

## Quick answer

 We extract every JSON-LD block, validate against schema.org, and score against Google's rich-result required/recommended fields.

## What it checks

- Valid JSON syntax

- @context is schema.org

- Required fields per type (Article, Product, FAQPage, HowTo, LocalBusiness, Event…)

- Recommended fields (for scoring)

- Conflicting/duplicate types on one page

## Where to find it in Lemwatch

 **Site details → SEO → Structured data.**

## How to fix

- Open the failing page in Google Rich Results Test to see the specific field.

- Add missing required fields (name, image, etc.).

- Remove duplicate schemas for the same entity.

- Re-crawl.

## FAQ

### Does more schema = better rankings?

 No — quality > quantity. Focus on rich-result-eligible types.

### Should I use microdata or JSON-LD?

 JSON-LD — Google recommends it exclusively.
